Answer:
Molecular mass is a number equal to the sum of the atomic masses of the atoms in a molecule. The molecular mass gives the mass of a molecule relative to that of the 12C atom, which is taken to have a mass of 12
Explanation:
<u>Answer:</u> The value of
for the equation is 
<u>Explanation:</u>
The given chemical reaction is:

The chemical equation for which the equilibrium constant is to be calculated follows:

As, the equation is the result of the reverse of given reaction. So, the equilibrium constant for the equation will be the inverse of equilibrium constant for the given reaction.
The value of equilibrium constant for the equation is:

We are given:

Putting values in above equation, we get:

Hence, the value of
for the equation is 
Antacids neutralise the acid made by your stomach. They are commonly used in conditions where it is helpful to neutralise the acid made in the stomach. For example, for acid reflux which causes heartburn. Most people who take antacids do not develop any side-effects.
